Located within the outer shell Il! is a separate treating tank unit including a supporting base 26 which rests on the floor or the same supporting surface on which the shell IU rests. This base 26 may or may not be attached to the outer shell I0, as desired. As shown, it is detached, and, for the purpose intended, it is of sufficient weight and diameter to afford a stable support for the parts carried thereby and now to be described.

Mounted on the base 26 is a spider frame 21 having an independent base portion 28 which is secured centrally on said base 25. As shown, the spider frame 21 comprises vertical leg portions 29 which are formed integrally with and extend upwardly from the base portion 28, the upper end portions 30 of said frame members extending incliningly upward and convergently with their extreme ends attached integrally to a bearing hub 3|. A vertical spindle shaft 32 has its ntermediate portion journaled in the bearing hub 3| on which latter the shaft is supported by a thrust collar 33 which is pinned to the shaft and rests on the upper end of the hub 3|, the lower end of the shaft 32 being journaled in a central bearing boss 34 provided on the upper side of the base portion 28 of the spider frame 21, while the upper end of the shaft is extended above the'collar 33 and has a circular supporting bracket 35 xedly secured thereon so as to rotate therewith and support a frame on which the treating tank is mounted, as will now be described.

While the bracket element 35 may be of any suitable form, it preferably comprises a circular plate portion which is cast or otherwise formed integrally with a hub portion 36 which is iastened on the upper end portion of the shaft 32 and is reinforced by triangular webs 31 formed integrally with the circular plate and hub portions. Extending diametrically across the top of the bracket element 35 and securely bolted thereto, as at 38, is a horizontal flat frame bar 39 having Vertical upstanding end portions 43, said upstanding end portions having axially aligned apertures therein for the reception of trunnions 4| and 42, respectively, provided at the opposite ends of a treating tank 43. The tank 43, which is of oblong form, is preferably extended equally on opposite sides of the axis of the supporting bracket 35, but, due to operative provisions to be presently described, one of the upright portions 40 at the end of the frame member 39 is located at a greater distance from the adjacent end of the tank 43 than the distance between the upright at the opposite end of said frame member 39 and the end of the tank adjacent thereto. Hence, the trunnion 4| is relatively shorter than the trunnion 42 and it is attached directly to a rounded protuberance 44 provided on the outer face of a circular plate 45 which is riveted or otherwise securely attached to the central portion of the adjacent end wall of the tank. The longer trunnion 42 at the opposite end of the tank is attached to an enlarged stem portion 45 projecting from the rounded protuberance 44 of the circular plate 45', which are similar to the portions 44 and 45, respectively, which support the trunnion 4|, said plate portion 45' being obviously attached to the adjacent end wall of the tank 43 in the same manner in which the plate member 45 is attached to the tank.

The tank 43, which is designated the treating tank, is provided to receive the shingles, usually in a standard bundle as ordinarily made up for commercial distribution, together with the requisite amount of the liquid treating material, the tank being set in the position shown in full lines in Figure 1 and broken lines in Figure 2 with its open side upward, said tank being given a quarter turn on its trunnions after a denite time during which the shingles are subjected to the soaking or coating effect of the treating material in which they are immersed in the tank to a position as shown in full lines in Figure 2, in which latter position the liquid contents of the tank is dumped onto the conical bottom of the outer shell IG, whence it is drained ofi through the outlet i4 and conducted by the spout |5 and pipe l5 back to the supply tank or source from which it was taken and delivered into the tank 43 through the valve-controlled nozzle 22.

Preferably the normal bottom of the tank |53 or the side 41 thereof opposite to its normally open side 48 is provided with a plurality of transverse elongated openings or slots i9 which are normally closed with shutter-like effect by a longitudinally slidable outer bottom plate or plates 50 having corresponding transverse openings 5| which latter are brought into registration with said openings 49 in the bottom 41 when the slide plate 50 is moved in one direction by spring elements 52 as will now be described.

The springs 52, of which there is preferably a pair, as shown, are attached at one end to a transverse cleat 53 provided on the under side of the bottom 41 of the tank, and at the opposite ends to a corresponding cleat 54 provided on. the under side of one oi the slide plates 50, as shown. There are two of said plates located one each near the opposite ends of the tank and being connected by a longitudinal flat bar 55 which is riveted or otherwise secured, as at 55, to the adjacent portions of the plates 5!) between the respective openings 5| therein. For the purpose of guiding the connecting bar 55 said cleat 53 has its middle portion offset, as at 51, to straddle the bar and a supplemental guide 58 of substantially the same form as the middle portion of said cleat 53 is attached to the under side of the tank bottom 41 between said cleat 53 and the cleat 54 on the slide plate 55. There is suiicient distance between the element 58 and said cleat 53 to provide a guide base of ample length for the bar 55 and said element 58 is also spaced suiiiciently from the cleat 54- to permit ample opening movement of the slide plate 50.

The connecting bar 55 for the two slide plates 50 is extended beyond the end of the tank 43 on which the longer trunnion 42 is mounted and provided with a transverse rounded head portion or shoe 59 which is constantly in slidable engagement with an arcuate cam plate or track member 6D which is securely attached, as at 6|, to the adjacent end portion of the supporting frame member 39, the springs 52 constantly urging the slide plate 50 in the direction of said cam plate or track 63. The attached end portion 5| of said arcuate cam plate or track G is located at a distance from the adjacent end of the tank 43 whereby the slide plate is positioned to close the openings 49 in the bottom 51 of the tank 43 when the tank is in the normal vertical shingle-receiving and treating position as shown in full lines in Figure l and broken lines in Figure 2, while the offset free end portion of said arcuate cam plate or track 6i! is warped away from the end of the tank sumciently to permit the slide plates 50 to move endwise to a position where the transverseopenings 5l in `said plates are in full registration with the openings 149 in the bottom 41 of the tank, at which time the tank is in the full line horizontal position as shown in Figure 2, which position is also indicated in Figure 3. In this position the liquid content of the tank, which has not been taken up by the treating action upon the bundle of shingles within the tank, is readily discharged through the open side of the tank and the now uncovered openings dein the bottom wall 41, which is now vertically disposed. With the tank 43 thus posi- `tioned and drained as to the free excess treating liquid, it is rotated rapidly about the axis `of the spindle shaft i2 so lthat the liquid which has entered and collected within the open spaces between the several shingle slabs comprising the bundle within the tank is, by centrifugal force. evenly distributed upon the overlapped faces of the slabs, not only between the'relativelyspaced portions but also between those portions which are in closer relation and even in intimate contact with each other, and at the same time, such of the liquid that is not absorbed by or taken up within the coating of the several shingles, is thrown off and discharged through the open side of the tank and the uncovered openings 49 into the outer shell it.

The length of time this whirling movement of the tank and resultant centrifugal action is carried on depends upon the character of the treating liquid and its relative density. In any event, however, a comparatively short time is necessary for the initial immersion and soaking of the shingles and the subsequent centrifugal action to thoroughly impregnate or coat the shingles and dry `them sufficiently for commercial handling and distribution in vthe bundle. vIn this connection, it is here noted that not only is the impregnation or coating and drying of the shingles thoroughly and expeditiously effected by the centrifugal action but it has the further advantageous effect of practically preventing the several shingle slabs from sticking together, because during such action the slabs are constantly tending to move apart from each other so that when they have become sufficiently dry there is very little possibility, if any, of adherence bel tween them.

As a practical means for holding the bundle of `shingles in the tank i3 during treatment, a pair of angular clamping members 52 are slidably mounted in the tank 113, said members S2 being stood on end in the opposite end portions of the tank when the latter is in its vertical position as shown in Figure 1 and being movable toward and from each other by a pair of toggle links t3 which are generally arcuate, as shown in Figures 3 and 4, and have diametrically opposite straight end portions 6d which are respectively attached, as at 65, to the inner vertical edge portions of said members 62 which directly abut and slide across the inner face of the adjacent longitudinal side Wall of the tank. The opposite ends oi the arcuate portions of said links `63 are pivotally attached, as at 66, to an operating and holding lever '61 at opposite sides of the axis of its pivotal attachment to said longitudinal side Wall of the tank, as at 68, said lever 61 having a detent lill which is engageable with the teeth of an arcuate rack 1li provided therefor on vthe upper portion of said side wall of the tank, by which provision the lever 61 may be operated to move said clamping members 62 toward 'or from each other, as may be necessary,

`and 'the adjacent end walls of the tank during `the whirling movement of the tank, said openings 142 also affording ample open .space to prevent complete obstruction of the .ends .of vthe bundle of shingles when the bundle is clamped between the members 1|, whereby the liquid in the tankxreaches the ends of the bundle .directly through said openings.

Suitable guide means (not shown) maybe provided for the bundle-clamping elements `6.2 other than the shuttered bottom of the tank '43 on which said elements B2 slide, but such supplemental guide means is not ordinarily required because .of the particular arrangement of the link members 63 and operatingflever 61 and the pivotal attachment of the lever to the central `portion of the adjacent side wall `of the tank. In this connection, it is noted that the peculiar connection between the operating lever and the bundle-clamping elements G2 and the attachment of the lever to theside Wall of the tank, as just above stressed'makesit unnecessary to provide any additional holding means to prevent the clamping elements 62 from moving ,out of the tank 43 during the whirling motion of the tank in its horizontal position, particularly because the weight of the elements H|52 with the bundle of shingles clamped therebetween is sufcient `to resist the centrifugal force and especially as `the preponderance of the `weight is between the axis of rotation and the shuttered bottom of the tank.

In order to support the bundle of shingles on `the clamping elements 62 in spaced relation to the shuttered bottom of the tank 43 and at the :same

time brace the angular plate members of theelements 62, diagonal stays in the form of flat bars 13 are provided as shown more clearly in Figure 4,

the bundle of shingles being placed in the tank edgewise to rest on said braces 13 with the opposite ends of the bundle disposed in opposed relation to the angular members 1| of the clamping elements. Thus, when the operating lever 61 is actuated to bring the elements 62 .in clamping relation to the ends of the bundle, the bundle is not only supported above the bottom of the tank, but the bundle is also centered between the opposite end walls of the tankso that there is ample space for the circulation of the liquid in the tank beneath the `bundle as Well as at the ends thereof, it being of course understood that the treating liquid may be supplied to the tank 43 in suhcient quantity to bring it to a level where it covers the top of the bundle and the bundle is thereby completely submerged in the liquid It is here further noted that the bundle of shingles is preferably clamped and positioned in the tank 14.3 before the treating liquid is supplied from vthe nozzle 22. In

this way it is not necessary for the operators` hands and arms to come in contact with the liquid, and, obviously, the bundle of shingles may, after treatment, be removed from the tank and handled by means of suitable tongs `orother lifting and handling devices.

iii.)

For convenience in manipulating the lever 61 vthe handle portion thereof may be extended beyond the open side of the tank, and to facilitate turning the tank on its trunnions 4I and 42, a handle member 14 is preferably provided at one end of the tank. In the vertical position of the tank 43 for the reception, treatment and removal of the bundle of shingles, it is thus maintained by its natural equilibrium because of the preponderance of the load being below the axes of the trunnions 4l and 42. However, special provision is made for supporting the tank in the horizontal position in which it is whirled about the axis of the spindle shaft 32. As shown more clearly in Figure 2, the tank 43 in its horizontal position rests With one edge portion upon a ledge 15 provided on an upstanding end portion 16 of a transverse frame bar 11 which is supported at its inner end on the circular bracket member 35 and secured thereto, as at 18, Extending diametrically opposed to the transverse frame bar 11 is a similar bar 19 having an up-turned outer end portion 88, said bar 19 being secured to the bracket member 35, as at 8l. Secured, as at 82, on the inner side of the up-turned portion 88 of the frame member 19 is a leaf spring 83, the upper end portion of which is normally disposed inwardly away from the upper end portion of the upright frame member 80, said spring having an outwardly extended angular end portion 84 which rides over the end of the member 88 and aifords a support for the adjacent end of the treating tank 4'3 when the tank is in its horizontal position as shown in FigureZ. In turning the tank 43 on its trunnions from the vertical shingle-receiving and treating position to the horizontal dumping and whirling position, the spring element 83 is depressed by the engagement of the adjacent end portion of the tank therewith and it snaps back to its normal position in supporting relation beneath the adjacent end of the tank after the latter has reached its horizontal position. In order tol release the spring element 83 from its supporting relation to the tank 43 to permit it to be swung back to the vertical positon, a knob 85 is provided on the outer end of a stem 86, which is slidably mounted in an aperture provided therefor in the frame member 8) and suitably attached at its inner end to the spring element 83, by which provision a pull on the knob retracts the spring from engagement with the tank 43.

Any suitable means may be provided for driving the spindle shaft 32 and controlling the starting and stopping thereof. As shown, a loose pulley 81 is mounted on the lower portion of the shaft 32 with its hub portion supported rotatably 0n the boss 34 extending upwardly from the base plate 28 of the spider frame 21, said loose pulley 81 being constantly driven by a belt 88 connecting it to a suitable motor or prime mover (not shown) Fixed on the shaft 32, just above the loose pulley 81, by means of a set screw 89, or other suitable fastening means, is a driving pulley S8 onto and from which the belt 88 is shifted from and returned to the loose pulley 81 by means of a shipper member 9| provided on the rear arm 92 of a pedal lever 93 which is pivotally mounted, as at 94, on one of the spider frame members 21 (see Figure 1), said pedal lever being yieldably held in its normal position by a spring element 85, in which position the belt 88 is entirely free from engagement with the fixed pulley 98 and riding only on the loose pulley or idler 81. In this connection, it is here noted that suitable braking means u (not shown) may be provided for stopping rotation of the'shaft 32 when the belt 88 is shifted olf of the ilxed pulley onto the loose pulley 81, which means may obviously be separately manipulated and controlled by the operator or included as a part of the belt shifting means in any approved manner.

In order to prevent the shingle treating liquid from passing out through the opening l2 in the bottom l l of the outer shell I0 through which the shaft 32 works, said opening is covered by a conical hood 9B, which is mounted on the lower end portion of the hub 36 of the bracket member 35 so as to rotate with the shaft 32. The peripheral portion of the hood extends with considerable overhang beyond the annular flange i3 surrounding said opening l2, said hood 96 not only effectively shedding the liquid due to its conical form but the liquid being also thrown oif by centrifugal force because of the rotation of the hood with the shaft 32.

In accordance with the present invention, as herein set forth, a shingle treating machine is produced which is simple and compact in structure, relatively low in height of its outer casing for convenience in access to and manipulation of the interior parts, and the relative construction and arrangement of the interior parts being such that the liquid treatment of the shingles and drying thereof is effected in an economical and highly efficient manner, and while the illustrated structure is a practical embodiment of the invention, it is obvious that considerable modification may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
